WINDOW POLE.

Application filed May 16, 1927. Serial No. 191,780.

My invention relates to winoows, and to a pole to be employed with thecasing and sash of the window for operating the sash.

In my copending application for patent,

No.'154,665, filed Dec. 14, 1926, I have shown a window adapted to slidein the casing upon riders from which it is adapted to swing at one endand to be removed from the rider. My present invention comprises aspecially constructed pole for use with this type of window so that thesash may be released and removed from the rider.

It is an object of the invention to provide a pole with which the sashmay be elevated and released from the rider and which will guard againstthe accidental removal of the sash from the operating pole when thewindow is being swung into reverse position.

Referring to the drawing herewith for a better understanding of theinvention, Fig. 1 is a broken perspective view illustrating the upperend of the casing and the sash employed therewith and showing theapplication of my invention thereto. Fig. 2 is a side elevation of thestructure disclosed in Fig. 1. Fig. 3 is a side elevation of theinvention with the handle broken away; and Fig. 4 is a front Viewthereof taken at right angles to the view shown in Fig. 3.

In the application of my invention, it is contemplated that there willbe a window casing including a jamb 1 having a channel 2 therein, withinwhich a sash 3 is slidable. The head 4t of the window has a lower planesurface.

The sash and easing disclosed in the drawings is of steel sheet metalconstruction, but it is of course understood that my invention may beapplied to any desired type of sash and casing in which the sash ismounted on the rider, as shown in my prior application, above referredto. The sash 3 is adapted to be mounted upon riders 5 shaped to fitwithin the channels 2'of the casing. The rider is of channel sheet metalconstruction and has on the side toward the sash a short slot or recess6 within which a laterally projecting pin 7 upon the sash is adapted tofit. The sash may also be secured to the rider in a slidable manner atthe lower end, if desired. It is to be understood, of course, that thereare riders at both sides of the sash slidable in channels 2 within thecasing and each rider having the same pin and slot connection with thesash.

The sash has approximately centrally of its width on the upper rail 8 aplate or bracket 9, upon which is a forwardly projecting arm 10 with anopening 11 therein to co-operate with the operating pole. The head 4 ofthe frame has an opening 12 therein immediately above the arm 10 uponthe sash.

The operating pole is adapted to engage with the opening 12 in thesotfit and also within the opening 11 of the sash bracket. It has.therefore, a handle 1% upon which is secured at the forward end a rod 15which projects axially from the handle for a suitable distance and thenis extended laterally at 16 and is again turned forwardly to provide afinger 17 to engage within the opening 12 in the head. At a point aboutcentrally of the rod 15 is a laterally branching arm 18 at right anglesto the rod 15, said arm having a finger 19 in approximate alignment withthe finger 17 and extending forwardly so as to engage within the opening11 in the sash bracket when the finger 17 is within the head of thewindow casing.

The operation will be approximately as indicated in Figs. 1 and 2. Thesash and rider will be raised upwardly to a point adjacent the upper endofthe casing and this may be done by introducing the finger 19 into theopening 11 in the sash plate and raising the sash until the finger 17upon the upper end of the pole engages within the opening 12 in thewindow head. The pole then constitutes a lever having a fulcrum withinthe opening 12 in the casing, the lower end of the pole constituting thepower arm. If the sash is lifted through the medium of the pole and thenswung forwardly into the room the action upon the sash will be to raiseit upward- 1y a sufficient amount to raise the pin 7 from the slot 6 inthe rider and drawing forward on the sash so as to move it free of therider and allow it to swing into the room toward the operator.

The pole may be then lowered, removing the finger 17 of the pole fromengagement with the window head and the sash may be carefully loweredinto reverse position.

I have found this operating pole of peculiar advantage in raising aheavy sash free of the rider and then allowing it to be low ered on itslower pivot into the room without danger of accident. A heavy metal sashis liable to swing accidentally into the room when freed from the riderand serious injury may be received by the operator. The

finger 19 upon the operating pole will be seen to be curved slightlyupward in Figs. 3 and 4: so that there will be little danger ofaccidental release of the sash. It is believed that the furtheradvantages of the device will be clear to those skilled in the art.

Having thus described my invention, What I claim as new and desire toprotect by Letters Patent is:

1. A window pole for the purpose set forth comprising a handle, a rodaxially of said handle at the forward end thereof, said rod being bentlaterally and then forwardly to provide a fulcrum finger to engage asupport, a lateral arm on said rod, a finger on said arm alignedapproximately with said fulcrum finger and adapted to engage awindowsash for the purpose stated.

mer es 2. A window pole comprising a handle, a rod at the forward endthereof, a forward fulcrum linger on said rod and a lateral sashengaging finger, said fingers being approximately aligned atone side ofthe axial line of said pole.

3. A window pole for raising and swinging a window sash in its frame,including a forward arm on said pole adapted to engage within an openingin said casing and forming a fulcrum, a lateral finger on saiclpolebelow said fulcrum adapted to engage said sash, whereby said pole maybeemployed as a lever to raise said sash. i

In testimony whereof I hereunto affix my signature this 11th day of MayA. 111927.
